Foam PVC Sheets

Foam PVC sheets sit at the sweet spot between strength, weight, and cost for sign-making, display builds, and light-duty construction. These expanded PVC panels (also called PVC foam board or Sintra) are lightweight, moisture-resistant, and easy to fabricate with common shop tools. Within Building Supplies and the Glass & Acrylic family, they provide a practical alternative to acrylic or wood where impact resistance and clean finishes matter.

Key benefits include a rigid, closed-cell structure that resists warping, low water absorption for damp environments, and a smooth, printable surface that accepts UV inks, paint, and vinyl. Many grades offer fire ratings and UV stabilization for outdoor use. The material machines cleanly, holds screws with pilot holes, and produces crisp edges for professional-looking results.

Choose thickness by application: 1–3 mm for short‑term posters and toppers, 3–6 mm for indoor signage and mounting, 10–19 mm for freestanding displays, routered letters, and dimensional panels. White matte is common for high-contrast graphics, with color options and gloss finishes available. Popular sheet sizes include 2440 × 1220 mm (8 × 4 ft) and larger formats, and many suppliers offer cut-to-size services to reduce waste.

Fabrication is straightforward. Score-and-snap thin stock with a sharp utility knife and straightedge. Use fine‑tooth carbide blades on table or circular saws for clean cuts; jigsaws or CNC routers handle curves and complex profiles. Drill with steady feed to avoid melting, deburr edges for a smooth touch, and heat-bend with a strip heater for folds. Bond with PVC cement, contact adhesive, or VHB tape. Apply vinyl films easily, or direct‑print via UV flatbed or screen print.

Safety tips: do not laser cut PVC due to corrosive fumes; use dust extraction, eye protection, and support sheets to prevent chatter.

Popular uses span retail signage, exhibition panels, point‑of‑sale displays, photo mounting, wall cladding, craft models, and outdoor signboards. Search terms: foam PVC sheets, PVC foam board, expanded PVC, Sintra board, lightweight plastic sheet, sign-making panels.
